android 科大讯飞语音+图灵机器人

前言：

  本文主要介绍一下之前学习的安卓平台下 “图灵机器人的设计”，希望能给爱学习的你到来更多的启发和兴趣。当然，随着时间的推延，技术的优化和进步，难免出现新技术的更迭，所以要经常充电学习...

  安卓开发：android4.2-5.0 


【注：2017-12-12】

  今天在同事手机上安装了一下试试，发现红米手机可支持，并且没有使用讯飞输入法也可以完成。

  毕竟代码编辑久远，当初的代码是在 android4.2 - 5.0 版本下开发的，如今的安卓版本更新换代快，终究会出现兼容问题，此外两年多没有碰安卓代码了，可能很难给以参考的伙伴以有价值的建议，希望多多进步咯 ...


一.前期准备：

  1.代码编写之前，在此提供 前辈大牛的视频讲解 ，其中涉及到了图灵账号的注册和效果实现

  2.其中注册网址为 图灵机器人官网 ，具体操作可看官方文档和之前的视频链接

  3.在此补充一个感觉很好的 参考博文 ，编写之前也参考了他的很多，主要还是学习众家所长嘛

  4.代码使用了讯飞语音，个人认为如果使用的讯飞输入法，同时下载了其语音，在编辑的同时即可使用，而此代码表示需要在联网状态进行语音的输入转化。

二.代码编写：

①. 权限设置

  1. <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
  2.     <!-- 讯飞语音权限开始 -->
  3. 	<uses-permission android:name="android.permission.INTERNET" />
  4. 	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  5. 	<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
  6. 	<uses-permission android:name="android.permission.RECORD_AUDIO" />
  7. 	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  8. 	<!-- 讯飞语音权限结束 -->

②. 项目展开状况如下所示

注意对应的jar包使用，之后会附上源码下载地址作为参考

③. 布局文件

④. 适配器设计代码如下

（/HoMotou/src/com/mo/adapter/ChatMessageAdapter.java）

  1. package com.mo.adapter;
  2.  
  3. import java.text.SimpleDateFormat;
  4. import java.util.List;
  5. import com.mo.bean.ChatMessage;
  6. import com.mo.bean.ChatMessage.Type;
  7. import com.mo.hoo.R;
  8.  
  9. import android.content.Context;
  10. import android.view.LayoutInflater;
  11. import android.view.View;
  12. import android.view.ViewGroup;
  13. import android.widget.BaseAdapter;
  14. import android.widget.TextView;
  15.  
  16.  
  17. public class ChatMessageAdapter extends BaseAdapter
  18. {
  19. 	private LayoutInflater mInflater;
  20. 	private List<ChatMessage> mDatas;
  21.  
  22. 	public ChatMessageAdapter(Context context, List<ChatMessage> mDatas)
  23. 	{
  24. 		mInflater = LayoutInflater.from(context);
  25. 		this.mDatas = mDatas;
  26. 	}
  27.  
  28. 	@Override
  29. 	public int getCount()
  30. 	{
  31. 		return mDatas.size();
  32. 	}
  33.  
  34. 	@Override
  35. 	public Object getItem(int position)
  36. 	{
  37. 		return mDatas.get(position);
  38. 	}
  39.  
  40. 	@Override
  41. 	public long getItemId(int position)
  42. 	{
  43. 		return position;
  44. 	}
  45.  
  46. 	@Override
  47. 	public int getItemViewType(int position)
  48. 	{
  49. 		ChatMessage chatMessage = mDatas.get(position);
  50. 		if (chatMessage.getType() == Type.INCOMING)
  51. 		{
  52. 			return 0;
  53. 		}
  54. 		return 1;
  55. 	}
  56.  
  57. 	@Override
  58. 	public int getViewTypeCount()
  59. 	{
  60. 		return 2;
  61. 	}
  62.  
  63. 	@Override
  64. 	public View getView(int position, View convertView, ViewGroup parent)
  65. 	{
  66. 		ChatMessage chatMessage = mDatas.get(position);
  67. 		ViewHolder viewHolder = null;
  68. 		if (convertView == null)
  69. 		{
  70. 			// 通过ItemType设置不同的布局
  71. 			if (getItemViewType(position) == 0)
  72. 			{
  73. 				convertView = mInflater.inflate(R.layout.item_from_msg, parent,
  74. 						false);
  75. 				viewHolder = new ViewHolder();
  76. 				viewHolder.mDate = (TextView) convertView
  77. 						.findViewById(R.id.id_form_msg_date);
  78. 				viewHolder.mMsg = (TextView) convertView
  79. 						.findViewById(R.id.id_from_msg_info);
  80. 			} else
  81. 			{
  82. 				convertView = mInflater.inflate(R.layout.item_to_msg, parent,
  83. 						false);
  84. 				viewHolder = new ViewHolder();
  85. 				viewHolder.mDate = (TextView) convertView
  86. 						.findViewById(R.id.id_to_msg_date);
  87. 				viewHolder.mMsg = (TextView) convertView
  88. 						.findViewById(R.id.id_to_msg_info);
  89. 			}
  90. 			convertView.setTag(viewHolder);
  91. 		} else
  92. 		{
  93. 			viewHolder = (ViewHolder) convertView.getTag();
  94. 		}
  95. 		// 设置数据
  96. 		SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  97. 		viewHolder.mDate.setText(df.format(chatMessage.getDate()));
  98. 		viewHolder.mMsg.setText(chatMessage.getMsg());
  99. 		return convertView;
  100. 	}
  101.  
  102. 	private final class ViewHolder
  103. 	{
  104. 		TextView mDate;
  105. 		TextView mMsg;
  106. 	}
  107.  
  108. }

⑤. 实现消息发送与接收的工具类设计

（/HoMotou/src/com/mo/util/HttpUtils.java）

  1. package com.mo.util;

  13. import com.mo.bean.ChatMessage;
  14. import com.mo.bean.ChatMessage.Type;
  15. import com.mo.bean.Result;
  16.  
  17. public class HttpUtils
  18. {
  19. 	private static final String URL = "http://www.tuling123.com/openapi/api";
  20. 	//"请自行申请apikey"
  21. 	private static final String API_KEY = "0905b3be27b638a58362d682529e2a3b";
  22.  
  23. 	/**

  32. 		Gson gson = new Gson();
  33. 		Result result = null;
  34. 		try
  35. 		{
  36. 			result = gson.fromJson(jsonRes, Result.class);
  37. 			chatMessage.setMsg(result.getText());
  38. 		} catch (Exception e)
  39. 		{
  40. 			chatMessage.setMsg("服务器繁忙，请稍候再试");
  41. 		}
  42. 		chatMessage.setDate(new Date());
  43. 		chatMessage.setType(Type.INCOMING);
  44. 		return chatMessage;
  45. 	}
  46.

  57. 					.openConnection();
  58. 			conn.setReadTimeout(5 * 1000);
  59. 			conn.setConnectTimeout(5 * 1000);
  60. 			conn.setRequestMethod("GET");
  61. 			is = conn.getInputStream();
  62. 			int len = -1;
  63. 			byte[] buf = new byte[128];
  64. 			baos = new ByteArrayOutputStream();
  65.  
  66. 			while ((len = is.read(buf)) != -1)
  67. 			{
  68. 				baos.write(buf, 0, len);
  69. 			}
  70. 			baos.flush();
  71. 			result = new String(baos.toByteArray());
  72. 		} catch (MalformedURLException e)
  73. 		{
  74. 			e.printStackTrace();
  75. 		} catch (Exception e)
  76. 		{
  77. 			e.printStackTrace();
  78. 		} finally
  79. 		{
  80. 			try
  81. 			{
  82. 				if (baos != null)
  83. 					baos.close();
  84. 			} catch (IOException e)
